Here’s Why Wine Bottles Have Hollow Bottoms

Written by hana

No matter their height or shape, wine bottles have one common feature: an interesting little cavity deep in the bottom. Until now, many of you thought there was a direct relationship to the quality of the wine. Well, not at all, according to bartender Stefan Sanchez. Something that piques your curiosity…

It all starts with glass blowers…

The specialist confirms that the reasons for this hollow bottom are historical. At that time, around the 4th century, the first bottles were made by glassblowers who, despite all their attempts, could not achieve a flat bottom. Contrary to all expectations, thanks to such an indentation, these craftsmen managed to further strengthen the bottom so that it is more stable on a flat surface and there are no sharp parts that could hurt people. This concave shape of the base of the bottle, also called the “bore”, was very practical to stabilize it and make it heavier. A technology that has proven itself.

So today, although wine bottles are now produced by industrial machinery and are much stronger structurally, the design concept at that time has remained. Although the technologies have advanced greatly, this “sting” is still relevant. Not only because it has become a tradition, but also for other practical reasons.

Two birds with one stone ?

In fact, according to Stefan Sanchez, this ripple is practical in many ways. It can be useful on two fronts: on one side, by holding your thumb on it, while supporting the bottle with your other four fingers, you can easily pour the wine. And above all in style! On the other hand, this hollow bottom helps collect the natural sediments that are produced over time. Its corner creates a narrow space where it is collected and therefore does not mix with the wine.

In addition, it has been observed over time that this concave shape helps to better distribute the pressure of carbon dioxide (CO2) found in sparkling wine.

In addition, the liquorologist determines that this ripple of the glass is only the strategic choice of winegrowers and that it has no effect on the quality of the drink.

Some golden rules for storing a bottle of wine properly

  • Ensure that the temperature of the environment in which wine bottles are stored is always as constant as possible. In fact, the changes risk changing the quality of the wine: too high or, conversely, too low temperatures can jeopardize its ripening. The ideal storage temperature is 10-12 ° C for white wine and 12-15 ° C for red wine.
  • Avoid storing wine bottles in the kitchen: This room is probably the most vulnerable to temperature changes that may affect wine preservation. It is best to store wine in a cool, damp place. Of course, a wine cellar would be perfect. But the closet will do.
  • Warning: Always keep wine away from light. Whether the light is natural or artificial, it can lead to oxidation and alter wine. So bet on a dark environment or with a soft and light sheen. Alternatively, you can also store the bottles in a wooden box or thick cardboard box.
